Texas Instruments and AirHop Communications, a leading provider of advanced radio access network (RAN) intelligence solutions for heterogeneous networks (HetNet), announced their collaboration to integrate AirHop’s eSON advanced self-organising network (SON) software on TI’s KeyStone-based small cell system-on-chips (SoCs).
With this integrated solution, developers using TI’s TMS320TCI6612, TMS320TCI6614 and TMS320TCI6636 SoCs will be able to design small cell base stations that will facilitate operators’ ability to deploy heterogeneous networks.
To meet escalating demand for mobile data, network operators are turning to small cell base stations to increase capacity and complement existing macrocell networks. The resulting HetNet requires SON technology specifically designed for small cell networks to actively optimise system capacity and manage inter-cell interference.
The combined TI and AirHop solution helps base station vendors get to market quickly with high-performance small cells that satisfy telecom operators’ requirements for HetNet applications.
TI’s scalable KeyStone architecture includes support for both TMS320C66x digital signal processor (DSP) generation cores and multiple cache coherent quad ARM Cortex-A15 clusters, for a mixture of up to 32 DSP and RISC cores.
In addition, TI’s KeyStone architecture includes fully offloaded, flexible packet and security coprocessors and capacity expansion for SoC structural elements such as TeraNet, Multicore Navigator and Multicore Shared Memory Controller (MSMC).
These structural elements provide a seamless integration between the DSP and ARM RISC cores, allowing base station developers to fully utilise the capability of all processing elements, including the cores and enhanced AccelerationPacs.
AirHop’s eSON software delivers multi-cell coordination and optimisation that can be deployed in fully distributed, centralised or hybrid architectures and, for maximum flexibility, can be located anywhere in the core network cloud and on a variety of network edge devices.
TI’s KeyStone multicore SoC architecture enables more efficient measurements from the lower-level PHY stack, required by the higher-level SON algorithms, resulting in optimised SON solutions for customers.
